Folding Stand Securing Mechanism for Stable Portable Power Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compact power tools like benchtop table saws require a secure and portable stand that can elevate them to a convenient work height, but existing solutions lack a user-friendly and stable securing mechanism.
Innovation Solution
A foldable stand with pivotable legs and identical securing mechanisms that use curved arms and cradles to securely grip the power tool's frame members, allowing easy locking and unlocking without tools, and can be folded for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a compact power tool is placed on a stand, then the work height is elevated to a convenient level, but the tool may become unstable or fall without proper securing
Solution Approach 1:
A securing mechanism acts as an intermediary between the stand and the power tool. The mechanism includes a base plate that contacts the tool and a securing arm that can be positioned to engage with the tool's frame, preventing it from falling while maintaining the elevated work height
Solution Approach 2:
The stand is divided into separate functional components: the base structure for elevation, the securing mechanism for stability, and the tool-contact surfaces. This segmentation allows the securing function to be added without compromising the height-elevation function
2Reliability
If a securing mechanism is added to the stand, then the tool stability is improved, but the device complexity increases
Solution Approach 1:
The securing mechanism is designed to be self-contained and self-operating. The securing arm uses spring biasing to automatically engage with the tool when placed on the stand, and can be manually disengaged by lifting the tool. No additional power source, controls, or complex mechanisms are required
Solution Approach 2:
The securing arm serves as a simple intermediary component that bridges the gap between the stand base and the tool. It provides the necessary securing function through a single mechanical element rather than a complex system of multiple components
3Adaptability or versatility
If the stand is made foldable for portability, then the storage efficiency is improved, but the securing mechanism reliability may be compromised
Solution Approach 1:
The stand is segmented into collapsible leg sections that can be folded together for portability, while the securing mechanism is designed as a separate, rigid component assembly that maintains its structural integrity during folding and unfolding operations
Solution Approach 2:
The securing mechanism is pre-configured in a locked position that engages automatically when the stand is assembled. The spring-biased securing arm is preliminarily positioned to ensure immediate engagement with the tool, preventing any instability during the transition from folded to unfolded state

AI summary
A folding stand with a pivoting securing mechanism to secure an object to the stand is disclosed. The stand may include two rails in the same horizontal plane and a securing mechanism that pivots about an axis which is perpendicular to that horizontal plane. The securing mechanism may be positionable in a locked and an unlocked position. The securing mechanism may include one or more arms that extends over a portion of the object in the locked position.
